Impact of two oral doses of 100,000  IU of vitamin D 3 in preschoolers with viral-induced asthma: a pilot randomised controlled trial

ConclusionTwo oral boluses of 100,000  IU vitamin D3,once in the fall and once in the winter, rapidly, safely, and significantly raises overall serum vitamin D metabolites. However, it is sufficient to maintain 25OHD ≥ 75 nmol/L throughout 7 months in only slightly more than half of participants.Trial registrationClinicalTrials.gov,NCT02197702 (23 072014).
